We're also falling prey to the trap of the majority in some of our thinking. Almost subconsciously we're drifting into a "white history" which is exclusively military, and a "black history," which we're seeing as exclusively one of servitude. Obviously, those are gross oversimplifications. As I've said before, in American culture there are 8 ways to be black and only 1 way to be white. There were people who we today would have considered "white" by background and appearance today who were held in slavery in the South and subjected to second class citizen status in the North. Again, an oversimplification but a truth. It would be a valuable experience to do an Underground RR scenario as you've described, because most of us are accustomed to the history of the majority, never stopping to consider that one ancestor in our pasts could have propelled us into the history of the minority.
